Cl-llLlAN MILL.

SPECIFICATION forming part of Letters Patent No. 709,689, dated September 23, 1902. Application filed January 11, 1902. Serial No. 89,365. (No model.)

To all whom it may concern:

Be it known that we, GEORGE F. W ADDELL and WILLIAM J. EVANS, citizens of the United States,residing at Anaconda,Deerlodge county, Montana, (post-office address Anaconda, Montana,) have invented certain newand useful Improvements in Ghilian Mills, of which the following is a specification.

This invention pertaining to improvements in the construction of Ohilian mills will be readily understood from the following description, taken in connection with the-accompanying drawings, in which- Figure 1 is a vertical section of a mill embodying our invention, the section being taken on line ct of Fig. 2; Fig. 2, a plan of the mill; Fig. 3, a side elevation of the spider and driver, part appearing in section in the plane of line b of Fig. 2; and Fig. 4., a plan of the spider, the shaft appearing in section in the plane of line 0 of Fig. 3.

In the drawings,1 indicates the base; 2, the pan; 3, the die; 4, the screens; 5, the curb; 6, the shaft-bearing in the pan-bottom; 7, the main shaft; 8, the driving-shaft; 9, gearing connecting the driving-shaft to the main shaft, all the parts thus far referred to being of ordinary construction; 10, a sphere mounted upon the shaft and capable of vertical movement thereon and splined thereto or not, as may be desired; 11, the spider-hub, provided with a spherical center engaging the sphere; 12, cap secured to the hub and forming the upper portion of the spherical hearing therein; 13, journal-arms projecting rigidly from the spider, the spider being shown as arranged for three rolls; 14, rolls with their hubs bearing upon the journal-arms, the lat ter being provided with keeper-nuts to prevent the outward displacement of the rolls; 15, drag-arms projecting outwardly from the spider-hub between the journal-arms, these drag-arms being horizontally slotted at their outer extremities in the illustration; l6, journal-pins vertically disposed across the slots in the drag-arms; 17, the driving-disk, the same being splined to the main shaft above the spider and shown as having the usual annular water-pan form and the usual discharge spouts; 18, drag -bosses projecting downwardly from the driving-disk, their lower ends being substantially in the plane of the slots in the drag-arms of the spider; l9, journal-pinsfirmlykeyed into these bosses and projecting downward therefrom; 20, links, one for each drag-arm, connecting the journal-pins of the drag-arms with those of the drag-bosses, these links being so thin as to have vertical play in the slots of the dragarms and also upon the journal-pins of the drag-bosses; 21, the usual scrapers or distributors carried by the driving-disk; 22, an adjusting-nut threaded on the upper portion of the main shaft and coupled to the driving-disk and serving to vertically adjust the latter, and 23 a lock-nut for the adjusting-nut.

The main shaft transmits the driving power to the driving-disk, and this disk drives the spider through the medium of the drag-bosses, 850. The spider with its rolls may rise and fall independently of the driving-disk, and it may also rock upon the sphere, the flexible character of the link connections permitting these free motions of the spider and rolls. The rigid journal-arms 13 upon the spider give it great radial dimension and produces a peculiarly rigid and satisfactory roll-carrying structure.

We claim as our invention-- 1. The combination, substantially as set forth, of a main shaft,a sphere mounted thereon, a spider-hub loosely mounted on the sphere, journal-arms projecting rigidly from the hub, rolls mounted on the j ournal-arms, a die codperating with the rolls, drag-arms proj ecting from the hub, j ournal-pins carried by the drag-arms, arotary annular pan discharging on the die and rolls, secured to the shaft above the hub, journal-pins projecting from the bottom of the rotary pan, and links connectin g the j ournal-pins of the water-pan with those of the drag-arms.

2. The combination, substantially as set forth,of a main shaft,asphere mounted thereon, a spider-hub mounted on the sphere, journal-arms projecting from the hub,rolls mounted on the journal-arms, a die cooperatingwith the rolls, drag-arms projecting from the hub, journal-pins carried by the drag-arms, a driving-disk secured to the shaft above the hub, journal-pins projecting from the driving-disk 5 to positions in front of the drag-arms, and

links connecting the journal-pins of the driving-disk with those of the dragarms, said links having vertical play upon said journalpins.
